Abstract
A cross-belt sampler (100) for material (70) on a belt-conveyor (60) has a cutter head (50), where the cutting edges (9) of the side plates (3,4) lie on lines co-incident with the axis of rotation (1) of the cutter head (50). The rear plate (5) lies on a plane parallel to the axis of rotation (1) and a truncated plate (6) eliminates a sharp corner in which the material (70) may be compacted. The axis of rotation (1) of the cutter head (50) is offset a distance (28) relative to the longitudinal axis of the belt conveyor (60).
Claims17
A cutter head for a cross-belt sampler for the sampling of a flowing stream of material on a belt conveyor, the cutter head being of a type having a pair of side plates interconnected by a rear plate and top plate, leading edges of the side plates defining a sampling opening, and the cutter head being operable for rotation through a sampling cycle about an axis of rotation parallel to a longitudinal axis of the belt conveyor, wherein:
- the leading edges of the side plates are inclined and, when orthographically projected into a plane perpendicular to the motion of the solids on the belt, fall on two straight lines which meet at the axis of rotation of the cutter head.
